However, such energy conversion cannot be realised …

http://adolfodesanctis.it/?p=955#respondMon, 19 Feb 2018 17:40:34 +0000http://adolfodesanctis.it/?p=955After more than 50 years of technological advancements in microelectronics, the measurement of the properties of electronic devices is a well-established field. However, graphene and two-dimensional materials are revolutionising this field, presenting new challenges for scientists and electronic engineers. Some peculiar phenomena observed in graphene require a careful choice of …

This year I have added some more gear to my 200 mm Newtonian, which made life much better but not necessarily easier. I finally completed the auto-guide system for my SkyWatcher HEQ5 mount (the old model, not the SynScan version….). …

They are responsible for the colour of stained glass, found for example in the windows of churches, or in the famous Lycurgus Cup, a 4th century Roman glass cup which displays a different colour depending …

In the university of Exeter, me and my colleagues used a chemically-modified form of …
